Thanks for reporting this, but I already added this patch to linux-next today: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=f1ccbd181202c660b237b9bef0af277b980d5073 and will push the batch of 7 patches upstream either Friday or early next week. (I'm waiting to hear about two more patches first: a fix for a theoretical problem that's been discovered and a possible adjustment to the hints metadata.)
